Abstract

PURPOSE: A method for moving a grade using a secret code in a key telephone system is provided to enable a subscriber to perform a local loop call in one's call grade using one's secret code through any telephone by embodying a secret code to an extension subscriber in a key telephone system. CONSTITUTION: A subscriber(extension No. 20) having a secret code presses a recall button at other key telephone(extension No. 22) in other place without raising a handset, and dials a secret code(T1). If the inputted code is identified with one's secret code, a character string of "AUTH STA 20" is displayed on a liquid crystal display(T2). If the handset is not raised until 10 seconds are passed, the character string is erased and a call grade is not changed. If the handset is raised in 10 seconds, the character string is erased and a dial tone is caught. At this time, the subscriber occupies a wanted local loop and dials a telephone number(T3). Thus, the call grade of the subscriber is moved into the key telephone(extension No. 22), and a local loop call may be performed in the key telephone(extension No. 22) as the call grade of the subscriber.

The present invention relates to a method of moving a grade using a secret code in a keyphone system that allows callers to use their own call grades in other phones when giving and using different call grades to extension subscribers using the keyphone system.

In general, the key phone system is configured as shown in FIG.

That is, the control unit 1 for managing and controlling all functions of the key phone system; A memory section 2, comprising a program memory (ROM) 2A and a data memory (RAM) 2B, which stores contents necessary for operating the system; A data communication unit 3 which notifies the control unit 1 of the state of the trunk line and the station and transmits the information sent from the control unit 1 to the trunk line and the station; It consists of a matrix unit 4 for transmitting and controlling voice and various signals between the trunk line and the station or between the station and the station.

The keyphone system configured as described above is generally configured in three modes.

This means that the normal mode, which is the normal mode in which the key phone system is normally operated, and the state of the phone in the system when the key phone system is installed, i.e., the ring signal is audible, the LED of the corresponding button. Test mode for testing whether the keyboard is working or whether the characters are displayed on the LCD, and the program contents initially set to suit the user's needs, such as rings. It is composed of a program mode for changing the presence or absence of a signal. At this time, for example, if there is a mode conversion switch in the key phone, the switch operates in the normal mode when the switch is in the 'N' position, in the test mode when the switch is in the 'T' position, and the switch is in the 'P' In the position of, it operates in the program mode.

When the subscribers who use the above-mentioned key phone system are given different call grades during the trunk line call, the subscribers with higher grades (for example, long distance / international call allowance) are lower than their own call grades. If you use another phone that has a phone, the call rate is restricted, which causes a lot of inconvenience for the mobile subscribers in the office.

In view of the above, the present invention allows subscribers in a key phone system to be able to make a local call to their own call level without being limited to the call level corresponding to the other seated phone, even if the subscriber has a high call level. By giving a secret code to any phone, it is characterized in that it is possible to make a local line call with its own call grade with its own secret code.

In other words, after changing the mode and changing the mode to the program mode in the programmable key phone, press the 'hold' button and the dial designated as the secret code input field. Press the button corresponding to the extension number you want to enter the secret code, and enter the desired secret code using the dial button within 5 digits. Then, after confirming whether or not to continue inputting to another extension, repeat the above input process if you want to continue, and if you want to finish, press the 'speaker phone' button to cancel the field designation. Then change the mode to normal mode. In addition, if you want to delete the entered secret code because the secret code has already been assigned, enter the secret code designation field in the program mode and press the button of the station that you want to delete or press the '*' button to select a new secret code. The secret code is erased. Then, if you want to input again, press the button of the extension to repeat the secret code input process.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

2 is a flowchart illustrating a method of inputting a secret code to an extension that wants to input a secret code in the keyphone system of the present invention.

First, after changing the mode and changing the mode state to the program mode in the programmable key phone, the user presses the 'hold' button and the dial designated by the secret code input field (step S1). Then, by pressing the button corresponding to the extension number for which the secret code is desired, if there is no secret code already specified, the desired secret code is input using the dial button within 5 digits (step S2). If there is a secret code already specified in the step (S2) to delete the specified secret code by pressing the '*' button to delete (step S3). Then, after confirming whether to continue inputting to another station, repeat the above input process (steps S2 and S3). If you want to finish, press the speakerphone button to cancel the field designation, and then change the mode to normal mode. (Step S4).

3 and 4 are flowcharts illustrating a method of enabling a trunk line call to a call level in another phone with a secret code input as in FIG. 2. That is, FIG. 3 is a method implemented in a key phone, and FIG. 4 is performed in a general telephone. Here, an extension with a secret code is called 20 and an extension at any other place is called 22.

In a key phone, the call class is shifted as shown in FIG.

The subscriber who has the secret code (extension 20) presses the 'recall' button without holding the handset from another telephone phone (extension 22) and dials the secret code of his (extension 20). T1). After confirming that the secret code input in step (T1) matches the secret code of its own (extension number 20), if it is matched, 'AUTH STA 20' is displayed on the liquid crystal display panel (LCD) (step T2). . If you do not lift the handset for a certain period of time, e.g., about 10 seconds in step (T2), the contents displayed on the LCD will be erased and the grade will not be shifted. Since the information displayed on the display panel (LCD) is erased, the dial tone heard by the key system is heard. At this time, the desired trunk line is occupied and the telephone number is dialed (step T3). Accordingly, the call grade of extension 20 is moved to the keyphone telephone of extension 22, so that the call can be made to the call grade of extension 20 at extension 2.

When the telephone of any other station 24 is a general telephone, the call grade is shifted as shown in FIG.

Subscriber who has a secret code (Ext. 20) picks up the handset from another telephone (Ext. 24) and dials a dial designated as a function code for mobile class. Dial (step P1). Check if the secret code entered in the step (P1) matches the secret code of his (extension number 20), if not matched to sound an alarm, for example, 0.25 seconds interval, if the registration confirmation tone, For example, let it ring for 1 second (step P2). If at any time in the step (P2) does not occupy the CO line after a certain time, for example, 10 seconds have elapsed, the alarm sound that was sounded in the step (P2) is to be sounded, and if the CO line is occupied before 10 seconds has elapsed, the call grade is This completes the dialing of the desired telephone number (step P3). As a result, the call level of extension 20 is moved to the general telephone number of extension 24 so that the call can be made to the call level of extension 20 from extension 24.

As described above, according to the present invention, it is possible to improve work efficiency by allowing subscribers with a lot of activities in offices that use different call grades in the keyphone system to make calls to their call grades at any place. .
